Cetin's example, using a BindingSource will work fine. But you don't have to use a BindingSource to get this to work, you just have to understand what it is that you missed.

There are two ways (two different syntaxes) to specify databinding for any control if you're binding to a DataTable in a DataSet and this results in two distinct binding objects. The problem is that you can't mix and match ... you have to stay consistent throughout the form.

So, in other words, if you bound your ListBox with:

this.lstBackups.DataSource = _dsBackups;
this.lstBackups.DataMember = "Backups";

Then you have to use the following syntax with TextBoxes:

this.txtDescription.DataBindings.Add("Text", _dsBackups, "Backups.LastName")

But since you bound your ListBox with:

this.lstBackups.DataSource = _dsBackups.Tables["Backups"];

Then you must use this syntax for TextBoxes:

this.txtDescription.DataBindings.Add("Text", _dsBackups.Tables["Backups"], "Description");

The second option is the preferable methodology, BTW.
